I want to know more about the latest attempts to create synthesizers for singing. I would ideally like to know more about both the most widely respected algorithms/models as well as mainstream software or programs that implement them (whether free or proprietary). Can someone offer me resources that would give me a decent grasp of the above?
I chose to post this question on Signal Processing Stack Exchange since I know such software relies to some degree on signal processing type methods for analyzing or creating waves.
I'm very new to this area of research so any suggestions for where to start would be welcomed.
